OK heres the scene. I go out to the garage and back my 02 Cougar out and park it on a hill in front of the garage. Later I go back and get in it to move it back into the garage. It starts up and then quits and won't start back. It just cranks. If I pull it in the level and let it sit for a few days it will start back. It runs good and the only time I have this problem is when I park it on the hill in front of my garage. I'm thinking the fuel pump may be weak? The only code that is showing up is for the EGR valve. Any thoughts besides don't park it on that hill.

Thanks

 

Is the front of the car facing up the hill or down?
